In daily life, escalators have become a common means of transportation in public places in modern cities. The handrails on escalators are also a safe reliance for everyone to take the escalator. At present, the rubber material of the escalator handrails is very absorbent and easy to attach bacteria. In addition, the germs on people's hands can be cross-infected through handrails, which may be one of the potential threats to modern public health.
At present, such escalators are found everywhere in subways and shopping malls, and many people touch them every day. Especially during the epidemic, the hygiene of handrails has become the focus of many people's concerns. A study showed that the number of bacteria in escalator handrails is 17 times that of ordinary toilet handles. What is the current main anti-bacterial solution? The main plan in the future?
It is understood that most of the escalators in China currently use manual cleaning schemes, which are cleaned by cleaning staff at a fixed time and cleaned by using rags and mops. However, it is worth noting that this cleaning method can only clean the dust on the surface. It does not kill surface bacteria. In the event of a public health event like the new crown epidemic, a small amount of bacteria can also cause infection. In addition, this cleaning method only cleans for a specific period of time, and cannot be cleaned in time.
Is there any way to safely, conveniently and instantly kill the escalator? At this time, the UVC LED solution enters the perspective.
Affected by the epidemic, issues such as elevator safety, sterilization and disinfection have become hot topics of concern from all walks of life. It is found that from 2020 to the present, many elevator manufacturers have introduced escalator sterilization solutions. Domestic companies such as Schindler Elevator have launched innovative solutions-Ultra ultraviolet handrail sterilization device, which can treat escalators and moving walks. The belt is efficiently disinfected and sterilized to reduce the risk of cross-infection. The device is similar to a hollow box with a mirror design. It is installed inside the structure on the left and right sides of the escalator or moving walkway. The light-emitting surface of the device and the surface of the handrail The distance is kept close to 15 mm, and its structural characteristics will not affect human health.
Ultra ultraviolet handrail sterilization device
In May 2020, Hitachi Elevator put into use the sterilization and disinfection device installed on the escalator in Guangzhou South Station of Guangzhou Metro Line 2. The risk of virus cross infection.
Foreign technology has been applied to the sterilization of escalator handrails. The solution is being adopted by EHC Global Inc. ("EHC"), a global escalator and elevator foundry, and a Canadian vertical transportation manufacturer.
EHC Safety+Handrail Sterilizer
According to reports, EHC's handrail sterilization solution using Violeds technology has been installed on escalators and moving walks in various usage environments around the world, including airports, public transportation systems, commercial buildings, shopping malls, department stores, medical institutions, sports Stadiums, museums, government buildings, etc. For example, Ted Stevens Anchorage International Airport in Alaska, USA and James Armstrong Richardson International Airport in Winnipeg, Canada both use Violeds technology to sterilize escalator handrails.
The UVC LED solution uses the built-in UVC band, which is basically harmless to the human body, after irradiating the surface of the handrail, it can destroy the DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) molecular structure in the cells of pathogenic microorganisms such as bacteria, viruses The principle of death or reproduction cannot be replicated, and it has the function of sterilization and disinfection. Therefore, it can realize real-time sterilization and disinfection of the handrails of escalators. It has an effect on Escherichia coli, Staphylococcus aureus, etc., and the sterilization effect is as high as 99. %, which can reduce the risk of cross-infection of bacteria and viruses in crowded places.
